Dynamic Pricing & Algorithmic Price Creep

Prices set per person, per moment, by algorithm — surge pricing, personalised paywalls, loss-leaders that lock you into high-margin refills, quiet monthly creep — so the price you see is your predicted maximum.

An everyday example

A fare that rises after you search twice; a printer sold at a loss and ink at 80% margin; a subscription that grows 4% a year without notice.

What it can cost you

Paying your personal maximum rather than a market price.

Warning signs

  • The price changed when I came back.
  • The cheap thing needs expensive refills.

One thing to do

Compare in a private window and on another device, track prices over time, and price consumables and renewals over the full life of the product before the first purchase.
